Question

A river flows north at 4 miles per second and a boy swims straight across it at 2 miles per second is the river is 8 miles wide how far will the boy be from his starting point after crossing the river

Answer 1

16 miles (with the crazy number units given)

Step-by-step explanation:

Find out how long it takes to swim across....use this time times the flow rate to see how far downstream he travels.....before he goes over the dam!

2 miles per second ??? VERY fast ( that is 7200 mph)

8 miles / 2 miles/sec = 4 seconds to swim across

river flow is 4 miles per second <=======extremely fast!!

4 mi/sec * 4 s = 16 miles
